58ef0e5bb3 dell_rbu.txt: standardize document format
Each text file under Documentation follows a different
format. Some doesn't even have titles!

Change its representation to follow the adopted standard,
using ReST markups for it to be parseable by Sphinx.

Currently, the document is completely unformatted. Add
titles, do indentation, mark literal blocks.

0211a9c850 trivial: fix an -> a typos in documentation and comments
It is always "an" if there is a vowel _spoken_ (not written).
So it is:
"an hour" (spoken vowel)
but
"a uniform" (spoken 'j')

ad6ce87e5b [PATCH] dell_rbu: changes in packet update mechanism
In the current dell_rbu code ver 2.0 the packet update mechanism makes the
user app dump every individual packet in to the driver.

This adds in efficiency as every packet update makes the
/sys/class/firmware/dell_rbu/loading and data files to disappear and reappear
again.  Thus the user app needs to wait for the files to reappear to dump
another packet.  This slows down the packet update tremendously in case of
large number of packets.  I am submitting a new patch for dell_rbu which will
change the way we do packet updates;

In the new method the user app will create a new single file which has already
packetized the rbu image and all the packets are now staged in this file.

This driver also creates a new entry in
/sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet
size here before downloading the packet file.

The user should do the following:

 create one single file which has all the packets stacked together.
 echo the packet size in to /sys/devices/platform/dell_rbu/packet_size.
 echo 1 > /sys/class/firmware/dell_rbu/loading
 cat the packetfile > /sys/class/firmware/dell_rbu/data
 echo 0 > /sys/class/firmware/dell_rbu/loading

The driver takes the file which came through /sys/class/firmware/dell_rbu/data
and takes chunks of paket_size data from it and place in contiguous memory.

This makes packet update process very efficient and fast.  As all the packet
update happens in one single operation.  The user can still read back the
downloaded file from /sys/devices/platform/dell_rbu/data.

e61c0e336f [PATCH] dell_rbu: enhancements and fixes
BUG fixes:

  The driver used to allocate memory with spinlock held which has been
  fixed in this patch.

  The driver was printing the entire buffer when it received a invalid
  entry in image_type.  The fix is to only print a warning message and not
  the buffer.

Usability enhancements:

  It is possible that due to user error the /sys/class/firmware/dell_rbu
  entries might be missing, this can happen if the user does the following

	echo 1 > /sys/class/firmware/dell_rbu/loading
	echo 0 > /sys/class/firmware/dell_rbu/loading

  This will make the entries in /sys/class/firmware/ to disappear and the
  only way get them back was bby unloading and loading the driver.

  This patch makes the user recreate these entries by echoing init in to
  image_type.

This patch has been tested with Libsmbios and Dell OpenManage.
